Original application filed May 9, 190,7, Serial No. 372,729. Divided andthis application filed. lovember 6, 1908. Serial No. 461,328.

To all whom it Conc/ffm lle it known that we, EDGAR F. HATHAWAY andCHARM-:s l). Lixxixo, both citizens of the United States. and residingat Dorchester. in the countr of Suffolk and State of iil'assz-ichusctts.have invented en .improveuient in Detached Heddles or the like, of whichthe iollowii'ig description, in connection with the accompanyingdrawings, is a speciticatitm, like .letters on the drawingsrepresent-ing like parts.

Our invent-ion relates to detached loom elements, such es heddles or thelike, and more particularly to the constructioning or fashioning of suchdetached heddles and their assemblage in organized series, such thatthey may be capable of ready selection and separation.

This application is division of our prior cto-pending application,Serial No. 372,729, filed May 9, 1907.

ln the `.mvfingsz Figure l is a. side elevation of a metallic harnesscomposed of a plurality of individual detached heddles embodying oneforni of our invention andshown for sake. of illustration in connectionwith the separating mechanism of a werp-drawing inachinc; Fig. 2 is atransverse section, showing in elevation, one of the individual heddlcsof the harness shown in Fig. l; Fig. 3 is a similar view, showing theiii-Xt adjacent lieddle; Fig'. et is a similar rico, showing the h lleof Fig. 2 in relation to a lieddle-rc f .en ng device; Fig. d is adetached i'icw in side elevation, showing the action ot the releasingdevice in conjunction 'with' a separating and selecting mechanism: andFig. G is a detail of the releasing d= rice.

Vcierring to the drawings and to the embodiment of our invention whichwe have there shown for illustrativo purposes. we have there shown inFig. l the two ends of a `loom harness composed of detached heddlcs, theintermediate portion of the harness being broken away for theI sake ofsimplicity.

The licddlc iii-embers, instead of being woren or knit into nv'continuous structure,

as are the hcddlcs of ordinary cotton' harness, are independent Vordetached, and herein, alth gi not necessary, are cornposed of Vinet-alhcplates l. perforated at Q for the purpose of affording a heddle eye forthe control of oneor more warp threads. Vilhilc the heddles may besupport-ed 'in any suitable manner to form an organized series, they arepreferably provided at their upper ends with openings 3, through whichis inserted a. heddle supporting bar l adapted to sustain the heddlos ine. compacted series, arranged with their adjacent flat faces in Contactor close oroxiinity.

To facilitate the separation and selection of the individual heddles inaddition to the thread opening' 2 each heddle is preferably so fashionedbetween its edges, as by the provision of the releasing opening 5, as topresent a regular alternate variation in form between si'iccessivemembers of the series. This is provided for in the illustratedembodiment of-our invention .by forming the opening or perforation 5with extension projecting in the case of one neddle upwardly, as at t3(Fig. 2) and in the case of the next adjacent heddle downwardly, as at 7(Fig. 3). 'It therefore follows that, while the perform-ions or openings5 may be held in registration, the extensions (3 and 7 alternate insuccessive heddles, first up and then down and are maintained out ofregistration. This or other alternating characteristics in the formationof adjacent. heddles may be employed to select and separate successivehcddlcs from the series by means of a releasing menthe-r operating uponsuccessive heddles. l"` or this purpose there may be utilized an)vsuitable form of releasing nicniher adapted to coperate with thealtei-nate fashioning of the heddles. To illustrate one such releasingmember adapted to operato in connection with the particular torni otreleasing opening herein shown, and to illustrate thcreb'if' the utilityof the particular form of lieddlc disclosed, we have sboun a releasingor separating membra: 8 comprisirncr herein a rod 9 adapted to eX-tcnd'longitudinally through the perforations fi. being' provided at itshead 8 with a helical formation terminatingabruptly in the'shou'ldercdportion l0. lith the releasing member in position represent-ed in Fig.5. ii a partial rotation is imparted thereto in the direction of forwardinclination o't' the helix thereonl the shoulder 9,

which holds liacl-i tli.l f(.roi=io,=t lieddle, will soon be brought.into alinrfiiif-iit ivilii the lateral projections or '4". as theeas-:e .may be, of the perforation 7i, lea'if'ing the foremost l'ieddlefree to be advanced lengthwise the releasing member. A slight furthermovement ot the releasing member causes the helix to force the leadinglicddle to the end ofthe releasing member and discharge the saine toan)y suitable positioning device such, for exan'iple, as the positioningworm 11. Duringthis iiioveu'ient of' the foremost lieddle the next.:fling heddie, inasmuch as its lateral rch sing projection isalternated with the releasing projection of the preceding lieddle andspaced 190o therefrom, is held back and, in turn, holds back the entireseries or mass of heddles. lVhen,

however, the releasing member has completed a halic revolution, the sameoperation is performed with reference to the next succeeding heddleandso on, a. fresh heddle being released and discharged to thepositioning worin for cach half revolution of the releasing member. Ttwill be seen, therefore, that the' alternate variation in the fashioningof the heddle )'ierforations provides a means for readily separatingsuccessive heddles from the mass.

As more particularly illustrative of the manner in which theseparationof successive heddles in the specific type of harness showncanbe effected h v mechanism adapted to be utilized in'an ordinarywarp-drawing machine, We haveshown in Fig. 1 portions of a heddlereleasing mechanism adaptedto be used in such a machine and with thespecific form of harness Aherein illustrated. Aethrar in conjunctionwith the releasing member there is here shown a carriage 12 adapted tomove with moreor lessresistance upon asuitable support 1'3. so as tomaintain the mass of hcddles, shown at the left (in Fig. l) thereof, ina' compacted condition1 The inner edge. 13 of the said carriage has its'upper portion curvedso as to slightly bend the upper ends of'thcresilient heddle outward, causing each one to spring 'away' from themass as it is released, thereby in; creasing the effectiveness of theielease.

The releasing rod 9-extends to driving mechanism at the right (as viewedin Fig.

1), not herein shown, as does also the shaft- 14 for lthe positioningworm 11. lVith the advance, therefor, of the relcasingmemher andpositioning' worm, together" with' the worm support 15 and carriage tothe' right (as viewed in ["ig. 1) the hcddles may be individually andsuccessively ing worm 11,- which is caused to advance them andv finallyturn their `nifl-portions la rgement.

separated i from the mass and delivered Ato the position-' throughai'iproximatcly 900 to present the thread perforations 2 to thedrawing-in needle, as represented in Fig. 1.

lfliile we have shown and described herein one specific torni of ourin'ention, it is ro he understood that the saine is presented only forthe purl'iose of 'concrete illustration and that extensive deviationsmay be made from the details of construction herein shown withoutdeparting from the spirit of the invention. lt will be obvious also thatour invention not onli7 contemplates the assemblage of a pluralityIvOf-lieddles into `V a metal harness, but also the assemblage into anorganized series of drop heddles, sometimes called metallic drop bars crdrop wires for stop motions, which 'are employed inA connection with thewarp of a-loom.

Having thus described our invention we claim is; i,

1. As a new article of manufacture an inv dividual heddle having areleasing opening provided with a lateral enlargement.

2. The combination of a plurality of Iheddles or similar loom elementshaving releasing openings provided each with a lateral offset, theoffset in successive heddles being differentially located.

3. As a new article of manufacture an individual heddle or similar' loomelement comprising a flat metallic strip having a what 'threadingopening and having a heddle ieleasing o ening intermediate its ends,such 9 5 opening eing-provided 'with a'lateral ent. As a new article ofmanufacture a harness compr-ising a series of heddles each composed ofthin sheet metal having each a releasing opening with a 'lateraloffset', Ythe Aoffset in. successive heddlcs'pointing in oppositedirections.

As a new article of manufacture a harness comprising a series of heddleseach composed of lthin sheet metal having each a releasing openin with-a lateral offset, the offset in each a ternate heddle pointing upwardand in intermediate heddle-s point-v ing downward.
